TP Link M5 DECO Ring Spotlight Cam & Floodlight Cam

Hi all, I recently installed a TP-Link M5 DECO Mesh WIFI system and since then my Ring Spotlight Cam is constantly losing connection. Is there a fix for this yet as I've found multiple threads about this but no real fix? One of the mesh routers is probably 3 feet from the Spotlight Cam but is still only showing RSSI -69 at best when connected for the short periods. My second Ring camera a floodlight cam, seems to have a stable connection all be it at RSSI -68. It seems strange they both don't have great signal when I can stand next to them with an iPhone or other device and they show full signal. Before the mesh was installed I had a BT Smarthub 2 with both cameras connected to a £20 BT Essentials Wi-Fi Extender 300 which actually did a better job. Any help would be appreciated. Thanks
